This application claims benefit of Japanese Patent application No. 2007-160666 filed on Jun. 18, 2007, the contents of which are hereby incorporated by reference.

FIELD OF THE INVENTION

The present invention relates to an organopolysiloxane, a method of preparing the same and a cosmetic comprising the same. The organopolysiloxane of the present invention has specific amounts of side chains and crosslinkages, and thickens not only silicone oils but also other kinds of oils or unctuous agents to form paste compositions having no greasiness. It can also form an emulsion depending on structures of the side chains and the crosslinkages. The present method of preparing the organopolysiloxane comprises two steps, i.e., the first step to form the-side chain and the second step to form the crosslinkage, enables one to prepare the organopolysiloxane having specific amounts of side chains and crosslinkages.

PRIOR ART

Silicone oils are used as base oils in various applications such as cosmetic because they are safe to the human skin. Particularly, for skin care and makeup cosmetics, silicone oils having a low viscosity of 100 mm²/s or lower are widely used for the reasons that they are safe, spread smoothly, and give refreshing feel to the skin. However, due to the low viscosity, relatively large amount of a thickener is required to form a paste composition from the silicone oil. It is sometimes difficult to obtain a paste which is stable and homogeneous with no breed out of the silicone oil.

As a thickener for a low viscosity silicone, the Japanese Patent Application Laid-Open No. H02-43263 discloses a method of preparing a homogeneous paste composition by kneading a specific silicone polymer thickener and a low viscosity silicone under shear. It is known that significantly improved thickening effect can be attained by adding inert silicone oil during a production process of a silicone polymer according to J. Soc. Cosmet. Chem. Jpn., 27(3), 480-483(1993) regarding a method of preparing a silicone thickener and thickening effect thereof. However, addition of a large amount of the silicone oil causes greasiness of the paste applied to the skin.

Many cosmetics comprise not only oil components but also water. The aforesaid silicone polymer is difficult to disperse in such water-containing cosmetics.

To improve dispersion of silicone oils in water, the Japanese Patent Application Laid-Open No. H04-272932 and H05-140320 describe introducing a polyoxyalkylene group in silicone thickeners, and International Patent Publication WO/04-024798 describes introducing a polyglycerin moiety in a silicone thickener. However, these thickeners do not have good compatibility with unctuous agents other than silicone oil, for example, hydrocarbon oils and ester oils.

The Japanese Patent Application Laid-Open No. H09-136813 and International Patent Publication WO/03-24413 describe silicone thickeners which have long-chain alkyl groups to have good compatibility with hydrocarbon oils and ester oils. However, they do not thicken silicone oils satisfactorily.

SUMMARY OF THE INVENTION

An object of the present invention is to provide an organopolysiloxane polymer and a method of preparing the polymer which polymer has good compatibility not only with silicone oils but also other kinds of organic oils to form paste compositions having no greasiness.

The present invention is an organopolysiloxane having a main chain composed of the following repeating units (I), 2 to 199 side chain units (II) and 1 to 50 crosslinkage units (III) per 100 SiO units in the main chain, provided that the organopolysiloxane has at least 2, on average, crosslinkage units (III),

The organopolysiloxane of the present invention has specific amounts of side chains and crosslinkages to be able to thicken not only silicone oils but also other kinds of oils. It can also form a stable emulsion. The organopolysiloxane of the present invention is very useful for cosmetics comprising a mixture of different types of unctuous agents and water.

PREFERRED EMBODIMENTS OF THE INVENTION

The aforesaid repeating unit (I) constitutes a main chain of the organopolysiloxane of the present invention. In the repeating unit (I), R¹ is an organic group selected from substituted or unsubstituted C₁₋₃₀ hydrocarbon groups having no aliphatic unsaturated bond, a group represented by the formula, —C_(j)H_(2j)O(C_(k)H_(2k)O)_(b)R⁴, and a group represented by the formula, —C_(g)H_(2g)OCH₂CH(OH)CH₂O(CH₂CH(OH)CH₂O)_(c)R⁴. A plurality of R¹′ may be different from each other.

Examples of the hydrocarbon group as R¹ include alkyl groups such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, stearyl, and behenyl groups; alicyclic groups such cyclopentyl and cyclohexyl group; aryl groups such as phenyl and tolyl groups; aralkyl groups such as phenetyl group; and fluorinated alkyl groups such as trifluoropropyl, nonafluorohexyl, and heptyldecylfluorodecyl groups. Preferably, 50 to 95 mole % of R¹ is a methyl group and 50 to 5 mole % of R¹ is a hydrocarbon group, particularly an alkyl or aryl group, having 6 to 30, preferably 6 to 22, and more preferably 8 to 18 carbon atoms.

In the formula, —C_(j)H_(2j)O(C_(k)H_(2k)O)_(b)R⁴, j is an integer of from 2 to 20, preferably from 3 to 12, k is an integer of from 2 to 4, and b is an integer of from 2 to 100, preferably from 5 to 50. R⁴ is a hydrogen atom, C₁₋₃₀ hydrocarbon group, which may be substituted, or an acetyl group. In the formula, —C_(g)H_(2g)OCH₂CH (OH)CH₂O(CH₂CH (OH)CH₂O)_(c)R⁴, g is an integer of from 2 to 20, preferably from 3 to 12, and c is an integer of from 0 to 10, preferably from 1 to 4. Example of R⁴ include alkyl groups such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, stearyl, and behenyl groups and acetyl group, among which a hydrogen atom, methyl, butyl and acetyl groups are preferred.

The side chain (II) comprises an organopolysiloxane moiety grafted to the aforesaid main chain, R¹SiO, via a silethylene group. The side chain (II) can be formed by subjecting an organopolysiloxane to constitute the main chain and an or ganovinylpolysiloxane represented by the formula (XII) to an addition reaction before forming the after-mentioned crosslinkage (III), wherein the alkylhydrogensiloxane comprises at least three, per molecule, alkylhydrogensiloxane unit of the formula, —(Si(R¹)(H)O)—.

Alternatively, the side chain (II) can be formed by subjecting an organopolysiloxane to constitute the main chain and an organohydrogenpolysiloxane represented by the formula (XIII) to an addition reaction, wherein the organopolysiloxane has alkylvinylsiloxane units of the formula, —(Si(R¹)(CH═CH₂)O)—.

It is difficult to form a desired number of the side chains (II) and the crosslinkage (III) simultaneously, which will be discussed later.

R² is a C₁₋₃₀ hydrocarbon group having no aliphatic unsaturated bonds. R² may be different from each other and its hydrogen atom may be substituted. Examples of R² include alkyl groups such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, stearyl and behenyl group, among which methyl and butyl groups are preferred. In the formula (II), a is an integer of from 1 to 300, preferably from 5 to 100.

The present organopolysiloxane should have an average of at least 2, per molecule, crosslinkage —X— between R¹SiO and R¹SiO, represented by the formula (III). The crosslinkage can be formed by reacting the aforesaid an organopolysiloxane to constitute the main chain with at least one selected from the group consisting of the organopolysiloxane of the following formula (VIII) having vinyl groups, the polyoxyalkylene compound of the following formula(IX), the α,ω-diene compound of the following formula (X), and the (poly)glycerin compound of the following formula (XI), wherein the aforesaid alkylhydrogensiloxane has at least one aforesaid side chain (II) and at least two alkylhydrogensiloxane unit of the formula, —(Si(R¹)(H)O)—, per molecule. By the reaction, the aforesaid structures of the formula (IV), (V), (VI), and (VII) are obtained, respectively.

In the above formulas, R³ may be different from each other and is a substituted or unsubstituted C₁₋₃₀ hydrocarbon group having no aliphatic unsaturated bond. R⁸ and R⁹ may be different from each other and are hydrogen atoms or methyl groups, d is an integer of from 0 to 500, preferably from 5 to 300, e is an integer of from 2 to 100, preferably from 5 to 70, f is an integer of from 0 to 10, preferably from 1 to 5, m is an integer of from 2 to 20, preferably from 3 to 12, n is an integer of from 2 to 4, and p is an integer of from 4 to 20, preferably from 6 to 16.

An organopolysiloxane having the alkylhydrogensiloxane unit of the formula, —(Si(R¹)(H)O)—, is represented by the compositional formula, R¹ _(q)H_(r)SiO_((4-q-r)/2), wherein q is a number of from 1.2 to 2.5, and r is a number of from 0.001 to 1.0. The organopolysiloxane is preferably linear, but it may have a branch. The hydrogen atoms bonded to silicon atoms may be located at the ends of the organopolysiloxane molecule or the branch.

The organopolysiloxane having a vinyl group is represented by the general formula, R³ _(s)(CH₂═CH)_(t)SiO_((4-s-t)/2) wherein R³ may be different from each other and is a substituted or unsubstituted C₁₋₃₀ hydrocarbon group having no aliphatic unsaturated bond, s is a number of from 1.2 to 2.5 and t is a number of from 0.001 to 1.0. Examples of the hydrocarbon group include those listed for R², and methyl and phenyl groups are preferred. The organopolysiloxane is may be branched, but preferably linear. The vinyl group may be located at the ends of the organopolysiloxane molecule or a branch. The formula (VIII) represents an organopolysiloxane which has vinyl groups only at the ends and does not have any trifunctional siloxanes, i.e., T-units, or tetrafunctional siloxanes, i.e., Q-units.

Besides the aforesaid method, the organopolysiloxane with X represented by the aforesaid formula (IV) can be prepared by use of an organopolysiloxane having an alkylvinylsiloxane unit represented by the formula, —(Si(R¹)(CH═CH₂)O)—, to form a main chain and the organohydrogenpolysiloxane represented by the following formula (XIV)

wherein R³ and d are as defined above.

In the present organopolysiloxane, the side chain (II) is contained in an amount of from 2 to 199 units, preferably from 5 to 100 units, per 100 SiO units in the main chain. The crosslinkage (III) is contained in an amount of from 1 to 50 units, preferably from 2 to 30 units, per 100 SiO units in the main chain.

In 100 SiO units in the main chain, R¹SiO unit in the formula (II) and two R¹SiO units in the formula (III) are included, but the one having the substituent R² and the one having the substituent R³ are not included. An average of at least two crosslinkages (III) should be present per molecule. A norganopolysiloxane having less than two crosslinkages (III) may not retain oils satisfactorily. On the other hand, an organopolysiloxane having more than 50 crosslinkages may not be sufficiently swollen with oils. With an organopolysiloxane having less than two side chains (II) per total 100 SiO units in the main chain, high thickening effect and good usability may not be attained at the same time. Moreover, such an organopolysiloxane may not thicken both silicone oils and other kinds of organic oils. The side chains (II) in an amount more than aforesaid upper limit may hinder the formation of the crosslinkage (III). Besides the repeating unit (I), the main chain of the present organopolysiloxane may comprise trifunctional siloxane unit, R¹SiO_(1.5), or tetrafunctional siloxane unit, SiO₂, in amounts not to adversely affect the organopolysiloxane.

The present organopolysiloxane can be prepared by subjecting an organopolysiloxane used to form the side chain (II) and an organopolysiloxane used to form a main chain composed of the repeating units (I) to an addition reaction followed by forming the crosslinkage (III). In the process of forming the crosslinkage (III), an unctuous agent or oil may be present to swell the crosslinked product polymer. When an organopolysiloxane having a poly(oxyalkylene) group or (poly) glycerin moiety is prepared, the organopolysiloxane is preferably purified according to a known method, particularly the one described in the International Patent Publication WO/03-20828, after the preparation or formation of a paste composition of the organopolysiloxane.

As described above, the present method comprises the two-steps: addition of the side chain to the main chain organopolysiloxane and then crosslinking. For example, an organohydrogenpolysiloxane having at least three SiH bonds is subjected to an addition reaction with the organopolysiloxane of the aforesaid formula (XII) having a terminal vinyl group and then with a compound having unsaturated bonds at both ends represented by the aforesaid formula (VIII), (IX), (X), or (XI), to form crosslinkage. An organopolysiloxane with side chains and crosslinkages both comprising siloxane moieties can be prepared by addition-reacting an organopolysiloxane having at least three —Si—CH═CH₂ groups with the organohydrogenpolysiloxane of the formula (XIII) having a terminal hydrogen atom and then with the organohydrogenpolysiloxane of the formula (XIV) to form crosslinkages.

When the crosslinkage is formed before forming the side chain, efficiency of the addition reaction to form the side chain is significantly low. When the side chain and the crosslinkage are to be formed in a batch reaction, crosslinkages are formed before an intended number of side chains are formed to prevent formation of desired number of side chains, so that properties attained by the side chains may not be obtained.

Comparing reactivity with an organohydrogenpolysiloxane to form the main chain of the organopolysiloxane of the aforesaid formula (XII) and that of the compound of the formula (IX) or (XI) having unsaturated bonds, the former is higher than the latter. Consequently, when the crosslinkages are formed from the compound of the formula (IX) or (XI), an intended organopolysiloxane may be obtained even in a batch process. However, the two-step process is preferred to produce organopolysiloxane having stable quality.

As an organopolysiloxane to form the side chain, an organopolysiloxane having one vinyl group bonded to a non-terminal silicon atom such as 1,1,1,3,5,5,5-heptamethyl-3-vinyltrisiloxane in place of the organopolysiloxane of the aforesaid formula (XII), or an organopolysiloxane having one hydrogen atom bonded to a non-terminal silicon atom such as 1,1,1,3,5,5,5-heptamethyltrisiloxane in place of the organopolysiloxane of the aforesaid formula (XIII) can be used. However, an organopolysiloxane having a terminal vinyl or hydrogen atom is preferred for the reasons that reactivity at the terminal site is higher and a longer side chain is formed.

In the process of producing the polymer of the present invention, an inert silicone oil or organic oil may be present as described in the aforementioned J. Soc. Cosmet. Chem. Jpn., 27(3), 480-483(1993). The oil can be present either in the process of producing the siloxane side chain or in the process of producing the crosslinkage.

The addition reaction is performed in the presence of a platinum compound such as chloroplatinic acid, chloroplatinic acid modified with an alcohol, or chloroplatinic acid-vinylsiloxane complex, or a rhodium compound at room temperature or an elevated temperature of about 50° C. to 120° C. The reaction may be solventless or performed in the presence of an organic solvent as necessary. Examples of the organic solvent include aliphatic alcohols such as methanol, ethanol, 2-propanol, and butanol; aromatic hydrocarbons such as benzene, toluene, and xylene; aliphatic or alicyclic hydrocarbons such as n-pentane, n-hexane, and cyclohexane; halogenated hydrocarbons such as dichloromethane, chloroform, and carbon tetrachloride; and ketones such as acetone and methyl ethyl ketone. For cosmetic application, solventless reaction or reaction in the presence of ethanol or 2-propanol is preferred.

The organopolysiloxane obtained may be processed to a paste composition by kneading with an unctuous agent which is liquid at room temperature. When the organopolysiloxane is prepared under the presence of a liquid unctuous agent, an additional amount of the liquid unctuous agent can be used to make a paste. Alternatively, the organopolysiloxane may be processed to powder by removing volatile substances and then pulverizing the dried organopolysiloxane. Preferably, the organopolysiloxane is processed to a paste composition which is then incorporated in cosmetics.

To make a paste composition from the organopolysiloxane of the present invention, it is preferred to mix the organopolysiloxane with an unctuous agent which is liquid at room temperature followed by kneading the mixture under shear stress, whereby a paste having a smooth appearance is obtained. Kneading may be performed by a three-roller mill, two-roller mill, side grinder, colloidalmill, Gaulinhomogenizer, and DISPER, among which three-roller mill and the DISPER are preferred.

The organopolysiloxane of the present invention can be swollen with a larger weight of oil than that of the organopolysiloxane itself. This can be confirmed by the following method: Kneading, with a three-roller mill, an appropriate weight of the organopolysiloxane and the same weight of a liquid unctuous agent as the organopolysiloxane, then, placing the mixture thus obtained on a 100-mesh net and, after keeping the mixture on the net for 1 hour, confirming that there is no liquid unctuous agent exuded from the mixture.

A liquid oil or unctuous agent having a viscosity of from 0.65 to 10000 mm²/sec at 25° C. is preferred because of their good handling property. Examples of such unctuous agent include silicone oils, hydrocarbon oils, ester oils, animal or plant oils and semi-synthetic oils. When a mixing apparatus capable of uniformly heating contents of the mixer, for example, DISPER mixer, is used, an unctuous agent which is solid at room temperature can be used.

It had a viscosity ratio (%) of the composition with 20 wt % of the crosslinked organopolysiloxane to that of the composition with 25 wt % of the crosslinked organopolysiloxane of 3.2%, indicating larger dependency of viscosity on concentration. It also showed worse dispersion stability and sensuous properties than that of Example 1.
